Again, maybe, maybe not. It would depend on how the future game played out.Let me try again since I was unclear. We have been discussing D&D, so I assumed you'd stay within this system. If you established in 5e that dopplegangers were thin skinned and agile, would you keep the that way for other future campaigns using 5e and set within the same world if you had different PCs and/or players?
If you're asking if I would feel any obligation to do so, no I wouldn't. I read differnent stories. I watch different films. I play different campaigns.
Why is it a boon to be told that doppelgangers are grey and bald?I said that adding those details is a boon to people new to D&D, less creative than you are, or who do not have the time to create all those details themselves.
I was new to D&D once. I wasn't told that - I started with Moldvay Basic, and I never even encountered the 2nd ed AD&D description of doppelgangers until you posted it in this thread. Yet I feel absolutely no deprivation. That would not have been a boon to me.
There are two reasons why I think that it is not a boon. First, given that doppelgangers are shapechangers - that is what makes them interesting elements in the game - focusing attention on their "true" from distracts attention from their use in the game.
Second, should the need arise, for whatever reason, for a AD&D GM to describe a non-shapechanged doppelganger, s/he could either describe them from the picture (in which not onlhy are they bald, but have brains in lieu of scalps) or just make something up. The creativity needed to come up with something as vivid as "grey and hairless" is actually not all that much.
(Upthread you suggested that the picture wasn't enough to infer the harilessness because perhaps it was referring to a total lack of body hair. Has the question of whether or not doppelgangers have arm hair or leg hair ever come up in a game you've run? In over 30 years of GMing I've had hair colour come up and mater; and skin colour; and the size of body parts, in games where magic items don't automatically shrink or grow. But never the amount of body hair a humanoid has on its arms or legs.)
You are the one who described the 2nd ed book as offering an impressive degree of lore.You keep saying that it's worthless to everyone, which is fairly arrogant.
If by "impressive" you meant word count, then I agree. There are many words,. But I took you to be saying that it is useful or valuable lore. And I do not think that being told doppelgangers are grey and hairless is useful or valuable. For reasons I've given, I would even go so far as to say it unhelpfully distracts from what is interesting about doppelgagners.
No doubt there are some players who, having been told that doppelgangers are grey and hairless, have used that in their games. Suppose instead the author had written that doppelgangers prefer to dine on buns during holiday season, no doubt that would have had some use by some players too. Would that suffice to make it "impressive" lore?
My assertion is that 2nd ed's approach to lore - reams of repetitive, redundant and banal stufff - is not essential to D&D. And here you are, in effect, agreeing with me! Because you note that 2nd ed AD&D differs from what preceded it.D&D has always provided lore and pinned things down. 2e more than any other edition, but all editions do it.
Moldvay Basic didn't pin things down. OD&D pinned things down even less - if you look at the monster entries in Book 2 and Chainmail, you will see that they pin very little down. Your claim as to how D&D has "always" been is simply not true.
Given that I can compare books to film, film to painting, dance to music, and so on, I suspect that I can make fruitful comparisons between RPGs and other narrative art forms.RPGing is not like the others, so attempts to compare it to other art forms are flawed from the get go. Besides, I've already answered this several times in other ways in other posts by showing you how it helps new DMs, less creative DMs, and DMs with not enough time.pemerton said:Given that it is not, in general, true of any art form that depth is proportionate to desriptive minutiae, why would this be true of RPGing?
Be that as it may, you still have not answered the question. How does telling a new GM that doppelgangers are grey and bald add depth to their game? This question can be broken down into two parts: (i) why does knowing the true colour of doppelgangers add depth to a game? (ii) why does being told by someone else the true colour of doppelgangers add depth to my game?
You may recall that I described it as lore masquerading as advice. You are being taken in by the masquerade.Advice to a DM is, "If you want, you the DM can have dopplegangers follow PCs and try to catch them alone.". Lore is what they provided for dopplegangers. Lore can be very useful to DMs in planning encounters, but that doesn't make it advice.
When it says that a doppelganger might follow someone to an inn, it is not calling out anything distinctive about doppelgangers (eg inns, but not a boarding house). It is just making a suggesgtion about how a GM might use a doppelganger (in an inn). And it is an obvious piece of advice.
I find it hard to believe that it would never occur to you to have a doppelganger follow a PC to the place the PC is going (be that an inn, a shop, a stable, or wherever).
